Canvas permission panel
When privacy.resistFingerprinting=true, the QR code at https://web.whatsapp.com/ is not displayed.
The QR code will display if you click on the image icon in the location bar and then "Allow Data Access".

This works for me after allowing canvas access, however a page reload is required.
Did you reload the page or do you think it should work directly without reload?
This works for me after allowing canvas access and reload.
My point is that the average reviewer would not think of doing this, she needs some kind of pop up "Warning: resistFingerprinting has blocked something on this page, would you like to activate it? "

Correct. We disable the visual popup if the website tries to read canvas before user interaction. If it tries to read canvas after user interaction, you get a visual popup.
This isn't ideal, but WhatsApp is hopefully the most prominent website that deals with this. In the future hopefully we can improve this.
